I.D. of this flower much appreciated

Thanks in advance to anyone who can help me I.D. this flower, one of several I've converted to flower mandala images but have yet to identify.

Lily, sorry there are too many varieties for me to guess which.

 

Thanks, I was figuring it was likely some kind of lily, but the petals look quite different from the other lilies I've seen in my area.
